MARK-ATTACHING MACHINE.

Application filed October 6, 1922.

To all whom it may concern:

Be it known that I, JnNs HoL'rERMAND, mechanician, a subject of the King of Denmark, residing at Aarhus, Denmark, have invented new and useful Improvements in lriark-Attaching Machines; and I do hereby declare the following to be a full, clear, and exact description of the same.

Marking machines as hitherto used in laundries, cloth-cleansing works, dyeing works and so forth, are defective so far as they stamp 21 mark direct on the cloth, or on a tape or band to be sewed on the cloth by means of the hand or an ordinary sewing machine. This system requires a permanent marking of the cloth, 1. e., the laundries, especially expect the linen repeatedly sent to the same laundry, and the mark once put on must be used again. The drawback of this system is that the laundry has to spend much time, and be very careful so as not to repeat the same mark, which then, naturally, would be useless. Moreover, this system requires much skill, also, as far as the sorting is concerned, the person performing the sorting having to remember where each customers linen is placed, for, if he is to look out for every piece of linen, the sorting will be far too troublesome. Another essential drawback is that customers dislike the marking.

The machine herein specified fastens a perforated number to the cloth which is to be marked, made of fibre or other suitable material not susceptible to washing or dyeing processes, and which is easily removed. Generally the cloth is stronger than the mark tied on which can simply be torn off. Besides, the machine delivers a detailed specification of each order.

The arrangement and operation of the most essential working elements of the machlne will first be described with reference to Figures 1-17, whereupon the construction of the complete machine will be fully explained.

Tl e most important parts constituting the invention are a perforating contrivance perforating and cutting a mark from a strip of fibre which is then carried to aknotting apparatus and held firmly there as the mark lied on to the cloth that is to be marked, and a counter specifying the contents of each order and operated in harmony with the perforator and the knotting apparatus.

The most essential parts of an embodi- Serial NO. 592,890.

ment of the invention are shown on the drawing, partly diagrammatically, in Fig ures 1-17 complete machine.

The machine operates as follow'sz The' discs 1 (Figures 1 and 2) freely 'turna'b le on a fixed shaft 2 are furnished each with ten perforating punches 3. The punches are displaceable substantial in a radial di rection with respect to the discs. Finger 4 has a projection 5 through which a fibre tape 6 or other suitable material'is put into: a set of four vertically overlapping punches 3 at the slots 7 In discs 1 opposite punches 3 are a number of pins (not shown)- ar; ranged to mark the figure concerned-while punches 3 have corresponding holes. The

pins do not reach into the slot? when the punch is in the-position shown on the drawing, but when finger 4 presses a set of punches 3 toward the centre of the discs 1 a making the section a circular segment and" one halfof a ring Onturningthe segment the tapewilllbe cut off againstthe edge ofthe semi-circular ring. The drawing shows a perforating device" with four discs 1, and

the" perforated markwi'll accordingly show fourfiguresf: Allthe figures on one=of the discs are units, on thenext tons, and so on;

WVhen. the" disc with the units h-asvturned round-tones, the: disc witlr tens will: change itsfigure,- and then the following discs as v usual; The change" is efi ected in the" ordi-' nary wayas inautomatic counters by a pawl 9. 7

Thema-rk 10 (Figures 3 and 4) having been= perforated and cut off as specifiedg-the machine will carry itdovvn to the 11 bythe operator before he starts the machine; mark .down toetheknotting apparatus will be describedin the following and includes a:

reciprocating and swinging picker having a needle which when the mark is stillh'eld in the perforator picksiup the mark and after the samehas been released from the perforator performs its vmovements and transfers themark to a swinging lever which'in turn" carriesthomark down tothe cloth placed on the plate: 11. The mark is then held firmly I on the clothby said lever during the opera-- tions' ofthe knotting apparatus. As will be understood the perforator is placed some distance above the knotting' apparatus.

This latter apparatus comprises a needle bar 12 inwhich an ordinary sewing machine'needle 13 is fitted which in turn will pass through cloth 1 4 and: mark 10.* When the needle has reached its highest position and againreturned alittle the thread will form a noose which will be caught by a hook- 15 on a catch 16 which wi llmove downward with the thread whenthe needle continues its downwards inoven'ients back through the cloth. When theneedle has reached the position shown on,-Fig. 5 theknotter hook 17 willmove out and then return withtln double thread but only 1 so far that the knotter finger18 can pass vertically from its cloth that is to-be marked and which 'is-pla'ced on plate The means used-for carrying the meters position on Fi ure to that on Figure {3 thus lifting the double thread as seen on the drawing, while at the same time hook 1? turns round its own axis entwining the thread once. It will then be pushed through the noose made by the entwining as shown on Figure 7 and afterwards return with the double thread stretched out between finger 18 at one end and the catch and needle at the other end. 'When on this returning movement the point of the hook has come beneath the knotter finger 18 it will turn round one fourth so that the point of the hook turns against the knotter finger 18 as shown in Figure 8 and continuing its returning movement, it will get out of the noose of the thread (Figure 9). The plate knife 1%) slides along a slot 20 in the hook, and on being moved forward, it will cut the thread placed in the hook. At the same time the knotted finger 18 will make a movement perpendicular to the plane of the drawing and will thus clear the threads. On the drawing the slot 20 of the hook 17 is larger in width relatively to the diameter of the hook than what corresponds to the real dimensions, in order to more clearly show the knife. On the back of the knife 19 shown in retracted position in Fig. 10 is a flat spring 21, somewhat longer than the knife, and consequently reaching the threads before the knife (since the knife and the spring are displaced as a whole) thus pushing them into the slot of the hook, by which method the threads of the knot will be held when the knife he cut the threads (see Figs. 11 and 12). When the hook continues its return a little longer the knot will be securely tightened. The attachment of the mark to the cloth is now complete. As shown in Fig. 10 one end of the spring 21 has a curved shaped in order that the spring may bear against the knife and press the same against the wall of the slot to secure a proper cutting operation of the knife. in Fig. 11 the back of the hook 17, is shown, and the spring and knife are shown in their foremost positions. As shown in this figure the end of the spring has been straightened by the threads which are pressed in between the spring and the wall of the slot.

When the. knife has cut the threads and the spring 21 holds the thread end firmly, Fig. 12, the needle 13 continues its downwards movement thereby drawing the superfluous thread 22 out from the knot. As will appear from what is stated above the thread 22 is double from the point of cutting to the hook 1.5 of the catch 16. It will now be of no importance whether the part of the thread 22 held by the hook 15 solely will also be drawn out from the knot by the downwards movement of the needle 13 or that part remains in the knot. The hook 15 is provided with a little spring (shown in Figure 15). When the catch 16 moves down wardly from the positions shown in Fig. t to that shown in Fig. 5 the thread will be caught by said little spring and held. between the same and the hook 15 during the subsequentoperations of the knotter, until the needle bar 12 descends from the position shown in Fig. 12, thereby taking the thread with it. Figures etl4lonly show one knotting device, while the machine is furnished with two, i. (-2., two needles with one thread each are fitted in the needle bar, besides the catch 16 has two hooks as shown in Figure 15, and there are two knotter hooks 1.7, and two knotter fingers 18. Both knctters work simultaneously, and are operated by the same gear. The purpose of two knotters is to double the security of the tying on of the mark, which bythis method is tied on by two threads.

The last essential part of the machine'is the counting device, the object of which is to number the articles of each customer. A number of rings 23 corresponding to the various sorts of cloth to be marked or groups of the specification are placed on a tube 24, Figures 16 and 17. The outer side of the rings are furnished with figures from one upwarc The device shown can only number eighteen pieces for every group of the specification. The inner side of the rings are furnished with teeth 25 the number and distances of which correspond to the figures 26 on the outer side, and pawl 27, which is moved whenever the machine marks one piece, turns the ring by operating on the teeth of the inner side of the rings thus mak ing another figure appear at 28 which is a long slot in plate 29, and the figures of the ring will be level with the lower side of plate 29, a stereotype plate, on which opposite each ring is a term for the several articles in the specification to be numbered by the ring; 11s is evident from the drawing the tube 24 has a long slot 30 longitudinally through which the pawl 2'? passes and engages with the rings. Associated with each ring is a plate ring 31, engaging with the long slot in the tube 2 L by a tongue 32; Consequently the plate ring cannot turn round on the tube thus preventing the ring which is turned, from moving the adjacent ring. Space 33 is also created for the pawl 2? rendering the operation'more secure and also preventing it from moving an adjacent ring. Pawl 2? is moved through bar'il l, which is movable longitudinally, and marked with terms corresponding to those on plate 29. By moving the bar 35 1 forward or backward the pawl 27 can be made to engage with any ring, and thus number any desired detail or group of the specification or of which the same may consist. lVhen a customers linen has been numbered an ink cushion is pressed against the plate. W'hen a piece of a paper ill) rollis pressed against plate 29, and then torn off it represents a specified order sheet of the linen delivered by any customer. When the contents of an order have been numbered the counting device must be replaced in its zero position. 13y turning tube 24 to the right round its axis on the plane of the drawing (Figure 17) the rings on the tube will also be turned. On the outer side of each ring is furnished a projection 35. If a ring has not been moved during the counting or been moved but a little it will follow the tube on being turned until the projection catches against the opposite edge of plate 29 when the tube will be turned on without the ring. A stop is furnished on the tube preventing it being turned beyond the point where the projection 35 of a ring which has not been moved during the counting catches the opposite edge of plate 29. When the tube is turned as round as permitted by the stop all the rings will be in the same position on the tube, and on turning the tube back to the position shown on the plan all the rings will follow and the counter be in its zero position.

The specified motions of the machine are brought about by mechanisms which will now be described.

Pcrforator actuating means Fig urea 18, 30,

which is rigidly secured in a frame P The finger 4, by means of which the perforating punches 3 are operated to perforate the mark, rests at one end upon the uppermost end of shaft 2 and is connected at its other end by means of conical pivots K to a onearmed lever K that is pivoted at its uppermost end upon conical pivots K secured in said frame 1?. The lever K can perform a small swinging movement to the left of the position shown in Figure 18, thereby displacing finger 4 in a horizontal direction. This movement of lever K as well as the motions of the other essential working members of the machine is derived from a camsector O which in Figure 18 is shown in its uppermost position and which can swing downwards approximately 80. The man ner in which the cam-sector is operated will be described later on. The cam-sector O is pivoted upon a shaft O which is rigidly secured in the side-plates P and P of the machine casing. A catch arm K is rotatably mounted upon a stud K secured to the lower end of lever K Said catch arm carries upon a stud K a roller K When the cam-sector O is swung downwardly this roller is engaged by a protruding edge O arranged on one side of camsector and so formed that the lever K is swung to the left, whereby the finger 4' is displaced and presses the punches 3 to wards the perforating pins of the discs 1 so that the mark is perforated in the manner previously explained. During this swinging movement of the lever K the catch arm K is held in the positionshown in Figure 18 by means of a projection K on lever K \Vhen the roller K during the downward swing of cam-sector 0 reaches a second protruding edge 0* on the latter the lever K and finger 4 are retracted to the initial position shown in Figure 18.

lVhen the cam-sector is again moved upwardly the catch arm K will swing in a counter clock-wise direction around its pivot- K and finally engage a second projection K on lever K and consequently lever K and finger 4 will remain in the position shown in Figure 18 during the complete return stroke of cam-sector 0 Thus the punches 3 are not actuated'in this period.

The fibre tape 6, Figures 2 and 3, from which the marks 10 are produced, is wound upon a drum K, Figure 20, freely rotatable around a shaft K which is secured by means of screws K to the frame P The drum is held in position upon the shaft K by a split K From the drum K the fibre tape 6 is carried through a guiding member K having a spring K which serves to keep the fibre tape in an appropriate lowered position. From this guiding member K the fibre tape 6 is carried between a roller K journalled on the projection 5 of finger 4 and a pawl K swing ing on the'pivot of said roller, Figures 20, 42 and 43. The pawl K" is provided at its inner face with small pikes (not shown) which when the pawl is swung toward the left, Figure 43, engage the fibre tape and move the end of the same through the knife 8 previously described and into'the slots 7 Figure 20, of the perforating punches 3. At the movement of finger 4 to the left hand side the cutting of the fibre tape is effected simultaneously with the perforating of the mark, since the above mentioned rotatable cutting segment of knife 8 is provided with a crank K which is connected to a rod K, the bent end of which loosely engages an aperture in a lug K formed on the frame P Figure 20. The rod K is prevented from disengaging lug K by a splitl The loose engagement between rod K and lug K enables the former to swing through a small angle in a horizontal direction. As explained above, the knife 8 is mounted on the projection 5 of the finger 4. and thus when the latter is moved to the left, Figure 42, the knife 8 is moved bodily in the same direction. whereby crank K operates the cutting segment of the knife to cut off the perforated mark from the fibre tape.

The movement of the pawl K is effected by the motions of a horizontally reciprocating member M (which co-acts with the knotter hooks and will be further described in the following). A stud I 22 on said member M is connected by a link K to a stud K on one arm of a two-armed lever K freely turnable on a shaft K which is rigidly secured in the frame P of the machine. Said lever is connected by a rod K to an arm K rigidly mounted on pawl K When link K during a double-stroke of member M is moved from the position shown in full lines in Figure 42 to the position shown in dotted lines and back again, the pawl K is moved from the position shown in full lines in Figure 43 to that shown in dotted lines and back again, and hereby is the fibre tape advanced in the manner explained above. K are splits inserted through holes in the bent ends of the rod K Immediately above the series of perforator discs 1 there is arranged a plate K, Figure 18, which is secured to the frame P and provided with a plurality of pins (not shown), which when the finger 4tis displaced towards the left hand side co-act with apertures formed in a radially displace-able punch K whereby a designating figure such as a number or'a letter is perforated in the mark in addition to the number perforated by the punches 3. This designating figure is individual for each marking machine, so that no confusion can arise in the case of more marking machines being used in the same laundry.

The lowermost end of shaft 2 is inserted through a hole in a plate K, Figure 18, and clamped to this plate with screw nuts 1. while the plate in turn is fastened to the frame P by means of a screw K The conical pivots K Figure 20 are axially adjustable and can be clamped to the frame P by nuts K; the conical pivots K are in a similar manner clamped to the lever K To retract the perforating punches 3 and K to the initial inactive position a stud K, Figure 18, is by means of pins K secured to the displaceable finger 4 and works in slots in the discs 1 and the plate X. hen the finger 4 is moved to the right, this stud K forces the perforating punches 3 and K away from the discs 1 and the plate K so that the perforating pins (not shown) are retracted from the slots 7 and the perforated mark 10 (Figures 1-3), whereupon the latter is picked up by the needle of a picker (to be described in the following) and carried away to the knottin g apparatus.

19, 32 and 34.

The cam-sector O is provided at one side with a cam groove Figures 30 and 32, en-

gaged by rollers L journalled on studs L which are secured to levers L and L respectively. These levers are pivoted as shown in A igure 3a to a side plate P forming part of the machine casing. Two lugs L are formed integral with the side plate P and carry by means of screws L a trans verse piece L to which is riveted a conical pivot L. A shaft L to which the lever L is rigidly secured is journalled at one end by means of pivot L and bears with its other conical end in a corresponding conical recess in side plate P The lever L is mounted to swing freely upon shaft L be tween a shoulder L formed on the latter and the lever L Between the side plates P and P there is secured a shaft L, Figure 30, on which a lever L is mounted which is arranged to swing The lever L is by means of a pin L connected to a rod L which in its opposite end is connected to lever L by a pin L The lever L is by means of apin L pivotally connected to a picker L which carries a short shaft L the free ends of which extend on opposite sides of the picker. These free ends of shaft L are adapted to work in angular slots L produced in smallangle plates L (one on each side of the picker) that are secured by means of screws L (Figure 19) to theinner sides of the side plates P and P respectively, so that shaft L can be dis placed horizontally and vertically in said slots whereby the picker is moved from the position shown in full lines in Figures 18 and 30 to the position shown in dotted lines. The picker L carries a needle L which in the proper movement is stuck into the perforated mark and transfers the same to the mark carrying basket L which is positioned upon one end of a double armed lever L. The basket is also supported upon a supporting arm L Figure 81. The lever L and the arm L are provided each with a sleeve L and L respectively which are rotatably mounted upon pivots L5. These pivots are clamped to the side plates P and P respectively by means of nuts L The perforated mark is delivered from the picker needle into the basket L and held firmly therein by means of the fiat springs L The lowermost end of lever L carries by means of a pivot L a bell crank lever L one arm of which is connected by pivot L tte a rod L which by a pivot L is connected to theupper arm of leverL as clearly shown in Figure 30. The, otheriarm of lever L is provided with a projection L engaging a slot L formed in a, plate L4? which by means of screws L Figure 31, is secured to, the side plate P When the cam sector is swung downwardly the rollers L run in the cam groove 0 andjtherebythe levers L and L are noved tothe positions shown in dotted lines, In operation the picl'gerL and 27, is carried upon the is first moved bodily inhoriZontal direction liver the mark into the basket L where upon the latteris swung downwardly to theposition shown in dotted lines'above the plate ll'and and 'held 't-here until the mark flha's'been tied on to the cloth.

I The picker L" and the lever L thereafter at the return stroke of cam sector are moved back to their initial positions.

" As explained above with reference to Fig "ures'415 the knotting{apparatus includes" a plate 11 upon which the cloth to be marked is placed. This plate 11, Figures 18, 25 outer end of a' swingable knotter frame M which is pivoted at its inner end upon conical pivots M clamped to the side plates P and P by means of screw nuts M (Figure 19).

The outer end of'the knotter frame hil may swmg up and down towards and away from an'oose P Figure 18. which 1s secured to the side plates P and 'P so that the cloth to be marked is held firmly between" plate 11 and noose P during the knotting operation.

The oscillations of the "knotter frame M is effected by means oi cam sector which is provided with a stud ()torming the pivot for a tube M* tlir'oi1gl1 which a rod M may slide.

The lever M is provided at itsupperend with a pin M which engages a bifurcated member hl iormed on a two-part member 'M the two parts of which are secured to each other by means oi screws M and embrace theinner ends oi the knotter hooks 17. Both ofthese knottei" hooks are provided with a reduced portion M so seated in the member M that the knotter hooks can turn freely in said member, but will reciprocatewith the same when lever M is swung. The rotary'motions of the knotterhooks 17 are effected by means of the lever M which through a connecting rod-M is connected toa sleeve M.

In the upper side-,of this sleeve there is formed a recess in which a rollerM is 11 accommodated which is journalled on a short shaft- M and bears against screw threaded portions M of the knotter hooks 17. Thus it will be understood that the member M constitutes a kind of antifrict'ion screw nut which when displaced horizontally through the action of the lever M will bring the knotter hooks to perform turning movements.

As explained above with reference to the 1115 diagrammatical Figures 1044 each knotter hook 17 is provided with a plate knife 19 and a flat spring 21. The purpose and operat-ion'; of th'ese 'members have been fully explained-above; and their actuating means 13;?)

7 a projection M will now be described with reference to Figures 354:1. The knife 19 and the flat spring 21 are secured to a slide 11 which bears with its outer end M on the reduced cylindrical portion Mi of the knotter hook and with its inner end M on the cylindrical end portion of the screw threaded portion M of the knotter hook. V] hen the roller M at the outward stroke of member M engages the inner end M of slide M as shown in Figure 35 the slide with knife 19 and spring 21 is displaced towards the right hand side relative to the knotter hook whereby the thread will be cut in the manner previously described. After the cutting operation the knife will be retracted by the end M of the slide impinging against the block M of the knotter frame, and as the 'knotter hook 17 is still moved to the right hand side the slide M with the knife 19 and the spring 21 will remain stationary with respect to the knotter frame, and hereby the knife is retracted from the loop formed on the end of the knotter hook as explained above with reference to Figure 12.

The catch 16, which carries the hooks 15, Figures 25 and 27, is secured on the outer portion of a stirrup member 16" one end M of which is by means of stud hi pivoted to one arm of a bell crank lever M secured 011 shaft M while the other end M of the stirrup member 16 by a stud M is pivotally connected to an arm M on shaft M. In the position shown in Figure 25the other arm of lever 14 bears against on knotter frame MK The shaft 1 43 with. the ball crank lever M and the arm M is journalled on the conical pivots M secured in frame M The stirrup member 16 arrying the hooks 15 is so guided and actuated that it can move from the lowered position shown in Figure 25 through a substantial semicircular path to the elevated position shown in dot and dash lines in Figure 25 and back again, whereby the hooks 15 pass the left hand end of plate 11. T 0 this end an actuating bar M which is rigidly secured in member M by means of screws M and slides freely through a hole in the inner end of frame M is provided at its outer end with a finger M which is arranged to actuate the vertical arm of bell crank lever M so that this lever is swung in a counter clock-wise direction, Figure 25, when member 13 28 is displaced toward the left by means of lever M The vertical motion of stirrup member 16 is effected by means of roller M link M lever M and link M pivoted at one end by means of a stud M to lever M and at the opposite end by means of stud M to link M which swings on pivot M mounted on knotter frame M The stud M is pivotally connected to a liftingrod M the upper end of which is connected to run member 16 and 'uided each throu 'h an inclined slot M Figure 26, produced in an angle plate M secured on stirrupmember 16. Each knotter finger 18 is retracted from the knot by which the mark is secured to the cloth) in that way that the knotter finger at the upward stroke of stirrup member 16 impinges against the bottom of plate 11 whereby the knotter linger which is sufiiciently yieldable is forced downwardly and outwardly in slot M The downwardly extending part of catch 16 is guided between two lugs h l Figure 27 on ,knotter frame M In Figure 25 the position of camsector shown in dot and dash lines and the positions of the knotter elements shown in full lines correspond to the initial position of the machine when inactive. When the camsector is swung downwardly the thread is carried by the needle 13 on the needle bar through a slot in plate 11 and through the cloth 1 1 and the perforated mark 10 which is to be tied on to the cloth. Figures 19-54- illustrate the various positions of the camsector O and the knotter elements during the following return stroke (upward stroke) of the cam-sector and the downward stroke of the needle bar. In this period the knot: is formed. Figure shows that the camsector 01 has been swung upwardly from its extreme lowered position, in which moment the hook 15 is ready to grasp the loop formed upon the thread (not shown) by the initial downward stroke of the needle bar and to carry this loop beyond the left hand end of plate 11. A moment later the parts occupy the positions shown in the diagrammatical Figure 4-. In Figure 50 the camsector has been swung 40 upwardly from its lowered position. This figure corresponds to the diagrammatical Figure 5, in which the book 15 has carried the loop downwardly and the knotter hook 17 has been moved to the extreme left position in order to be ready to carry the thread above the knotter finger 18. In Figure 51 the cam sector 0 has been swung 52 upwardly from its extreme lower position, and this figure corresponds to the diagrammatical Figure 6, in which the knotter hook 17 has been moved towards the left while the knot- Hit) ter finger 18 has been moved upwardly. In Figure 52 the cam-sector has been moved 62 upwardly, and the knot-ter elements now occupy the positions shown in Figure 7, in which the knotter hook 1'? has been moved towards the right below the knotter finger 18. Figure 53 shows the position in which the cam-sector has been swung upwardly from its extreme lowered position. The knotter hook now as illustrated in Figure 8 has engaged the threads and performed a slight turning movement, so that it is clear to be moved towards the left and draw the threads through the loop already formed around thevknotter hook 17. In Figure 54 the cam-sector O has'been swung upwardly 7 6 which position corresponds to Figure 9. During the last part of the upward stroke of the cam-sector from-the position shown in Figure 54 to that shown in Fig. 25, which part will amount to 40, the knife 19 as shown in the diagrammatical Figure 12 is advanced in the knotter hook and cuts the thread, since the roller M, Figure 35, stops the knife carrying slide M and keeps the knife stationary while the knotter hook 17 is still moved towards the left to tighten the knot. Simultaneously the knotter frame M is lowered by means of rod M Figures 18 and 25, and the stirrup member 16 which carries the knotter fingers 18 is m ved upwardly whereby the knotter fingers strike the under side of plate 11, so that the knotter fingers are retracted from the knots as described above with references to Figure 26. The cam sector 0 has now completed its double-stroke, and the perforated mark has been tied on to the cloth by two sep arate knots.

The counter.

Figures 16-24, 282=9.

As explained above withreference to the diagrammatical Figures 16 and 17 the counter comprises a tube 24, Figures 19 and 21, upon which the numeral rings 23 may be turned by means of pawl 2? which engages the teeth 25 of the numeral rings to bring the desired figure 26 on the periphery of the ring to the position opposite the slot 28, Figure 21, in the stereotypic plate 29. The tube 24 is supported at its lower end upon the stationary frame member QflFigure 19, and is provided at its upper end with an end wall having a hollow hub N which is guided in the top portion of the counter casing O} and outside the latter is furnished with hand operated crank N that is secured to the hub by a pin N and provided with a handle N so that the tube 24 may be turned by hand. When the counter operates, the tube 24 should be locked in the position shown in Figures 19-24, and for this purpose crank N .is provided with a spring pressed pawl N Figure 19, which engages adepression formed in the upper side of the counter casing The pawl Y is provided with a head N by means of which the pawl may be lifted'to thereby release crank N and tube 24; The plate rings 31 arranged alternately with the numeral rings 23 are provided at their .inner periphery with projections (not shown) which fit in circumfe'ential grooves N formed: in the outer surface of tube 24. When the counter is assembleded up to the desired position and given a;

small turning movement whereby said projections on the inner periphery of the ring engage the desired circumferential groove N so that the ring 31 isheld in position on tube 24. It willbe understood that each plate ring 31 carries thenumeral ring 23 positioned immediately above the plate'ring. Vith this arrangement each ring 23 can easily be turned independently of the other nuineral rings by engagement with the selectively and axially adjustable pawl 27 Themachine is also provided with anadditional counter which counts the total sum of the figures presented by the rings 23 in slot 28. For this purpose the lowermost reduced end of tube 24, Fig. 19, carries three additional numeral rings N supportedby plate rings N The construction and mounting of these rings L and N is quite similar to that of the rings 23 and-31, so that eachnumeral ring N may be turned inde pendently of the other numeral rings N". Each numeral N is provided at-its outer periphery with thirty figures N (three sets of digits from O to 9) -Figure-22, and at its inner periphery with three recesses N -each of which may be engaged by a pawl N which is pivoted upon a stud N and serve to reset the rings N into the zero positions before the counter is to start a fresh counting operation; -The stud N is secured to the frame member Q and provided with a split N which serves to maintain the pawls N in position. The pawls N are pressed yieldingly outwardly by means of springs N one end of which is secured in-a stud N carried by the frame member while the other end of the spring bears against the rear side of the pawl as clearly shown in Figure 22. Opposite to the pawlsN there is produced an opening N Figure 22, in the tube 24 so that when-the latter is turned around its axis the pawls N will engage those recesses N which first appear in the opening N whereby the numeral rings N are. carried to the zero positions, whereupon the tube 24 is turned back againto its initial position. Here-by pawl N and ring N will be adjusted'in the position shown in Figure 22.
